桩的质量检验桩的质量检测方法主要有:可以检测承载力的静载试验、自平衡加裁试验、大应变动载检验,可以检测桩的完整性的小应变检验、声测检验、钻孔取心检验等方法。图26、图27为桩的质量检验。桩头清理作业在承台施工前,应进行桩头清理,并使桩顶钢筋形成喇叭口,与承台钢筋网连接成整体。用风镐进行桩头凿除清理,劳动强度大,工作效率较低,用液压顶破碎桩头,工作效率较高。清理后的桩头应平整,标高符合设计要求。
Pile quality inspection Pile quality inspection methods are: static load test can be carried out bearing capacity test, self-balancing plus punching test, large strain dynamic load test, you can test the integrity of the pile small strain test, acoustic test, drilling Coring test and other methods. Figure 26, Figure 27 for the pile quality inspection. Pile head cleaning operations in the cap construction, pile head cleaning should be carried out, and the formation of the top of the steel bell mouth, and the cap network to connect into a whole mesh. With picks hammer pile chisel removal, labor-intensive, low efficiency, with hydraulic top crushing pile head, higher work efficiency. After cleaning the pile head should be smooth, elevation meet the design requirements.
